GeForce GT 1030 vs GeForce GT 320

Intro

The GeForce GT 1030 has a GPU core clock speed of 1265 MHz, and the 2048 MB of GDDR5 memory runs at 1502 MHz through a 64-bit bus. It also features 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the GeForce GT 320, which makes use of a 40 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 memory works at a frequency of 790 MHz on this specific card. It features 72 SPUs as well as 24 Texture Address Units and 8 ROPs.

Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x.
The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image).
The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
